Hi @Niklas,
I’m seeing this same issue with a third party SIM I am using in Nigeria. We are also using a 2G Electron and seeing this loop of CGREG commands with 2,0 responses and never ending green blink.
We had our system working smoothly for 8 days and then all of a sudden last night it stopped connecting and has had this problem ever since. I saw your response is this thread: Electron suddenly stopped connecting about using the WITH_ACK and I have tried that but the Electron is still not connecting after flashing the new firmware and completely powering down multiple times. Have you seen this problem at all since your post a year ago? And do you think that the WITH_ACK change was the thing that fixed it for you?
Thanks,
Cole
